Question

Need help please! Will give it to the brainliest. Which expression models the bacterium's volume? Picture is below.

Answer 1

The expression C. $\pi (1)^{2} (0.5)$ cubic $\mu \mathrm{m}$ represents the bacterium's volume.

Step-by-step explanation:

Step 1:

The E. Coli bacterium is in the shape of a cylinder.

The volume of a cylinder is given by multiplying π with the square of the radius (r²) and the height of the cylinder.

The volume of a cylinder, $V=\pi r^{2} h.$

In the given diagram, E. Coli has a radius of 1 $\mu \mathrm{m}$ and a height of 0.5 $\mu \mathrm{m}$.

Step 2:

By substituting the values in the equation, we get

The volume of the E. Coli bacterium $= \pi (1)^{2} (0.5)$ cubic $\mu \mathrm{m}$.

This is option C.
